Every summer, as temperatures rise across British Columbia, wildfire smoke becomes a familiar visitor to the Lower Mainland. Whether it’s drifting in from the Interior or settling directly over Metro Vancouver, smoky skies don’t just affect our lungs — they take a real toll on our eyes too. If you’ve ever noticed your eyes stinging, watering, or feeling gritty on a hazy day, you’re not imagining it.
Here’s what’s actually happening to your eyes during smoke season, who should be extra cautious, and some simple ways to protect your vision until the skies clear.
How Wildfire Smoke Affects Your Eyes
Wildfire smoke is made up of fine particulate matter, ash, and gases that irritate any exposed surface — and your eyes are no exception. When smoke particles land on the surface of the eye, they can disrupt your natural tear film, leading to:
- Redness and burning
- A gritty or sandy sensation
- Excess watering (your eyes’ way of trying to flush out irritants)
- Blurry vision that comes and goes
- Increased sensitivity to light
For most people, these symptoms are temporary and settle down once air quality improves. But for certain groups, wildfire smoke can cause more significant discomfort.
Who’s Most at Risk
Contact lens wearers. Contacts sit directly on the eye’s surface, which means they trap smoke particles and irritants against the eye far more than glasses do. Many contact lens wearers find smoke season is when their lenses become genuinely unbearable to wear for a full day.
People with dry eye. If you already deal with dry, irritated eyes, wildfire smoke tends to make a existing problem noticeably worse, since it strips moisture from the tear film even further.
Recent LASIK or PRK patients. Mild dryness is a normal, expected part of healing after laser eye surgery, and smoky air can temporarily amplify that sensation. This isn’t cause for alarm, but it’s worth being a bit more diligent with lubricating drops during recovery if smoke rolls in.
Older adults, particularly those with cataracts. Aging eyes tend to produce fewer natural tears to begin with, so smoke exposure can hit harder.
Practical Tips to Protect Your Eyes This Smoke Season
- Check the air quality before heading out. BC’s Air Quality Health Index and apps like the BC Air Quality Subscription Service will tell you when it’s smart to limit time outdoors.
- Switch to glasses when smoke is heavy. If you wear contacts, giving your eyes a break on high-smoke days reduces irritation significantly.
- Use preservative-free artificial tears. Lubricating drops help rinse away particulates and restore moisture — keep a bottle in your bag or car during summer.
- Avoid rubbing your eyes. It’s tempting when they’re itchy, but rubbing can grind particles further into the eye’s surface and worsen irritation.
- Wear wraparound sunglasses outdoors. They offer a surprisingly effective barrier against airborne particles, wind, and glare.
- Run an air purifier indoors. A HEPA filter can meaningfully improve indoor air quality when smoke is thick outside.
- Stay hydrated. Proper hydration supports healthy tear production from the inside out.
When to See an Eye Doctor
Occasional irritation on smoky days is normal and usually resolves on its own. However, you should book an appointment if you experience:
- Eye pain that doesn’t improve with lubricating drops
- Vision changes that persist once air quality improves
- Discharge, swelling, or signs of infection
- Symptoms that interfere with daily activities for more than a few days
These could signal something beyond simple smoke irritation, and it’s always worth having a professional take a look.
A Long-Term Solution Worth Considering
If wildfire smoke season leaves you dreading another summer of fumbling with irritated contact lenses, it might be worth exploring whether laser eye surgery is right for you. Many of our patients tell us that ditching contacts altogether made smoky, dusty, and allergy-heavy days far more bearable — no lenses to remove, clean, or fight to keep comfortable when the air quality drops.
